SPECIAL ABILITIES

Death Throes (Ex)

When reduced to 0 or less hit points, an obsidian quasi-elemental explodes in a cloud of razor-sharp bits of obsidian. All creatures within a 30-ft radius take 6d6 damage. A DC 18 Reflex save reduces it to half. The save DC is Constitution-based.

Molten Glass (Ex)

A successful hit against an obsidian quasi-elemental with a piercing or slashing weapon (or piercing or slashing natural attack) that deals damage equal to its current HD opens a wound that spurts molten glass. The wound bleeds for 1d4 rounds and any creature within 5 feet must make a DC 18 Reflex save or take 2d8 fire damage from the splash. A new save must be made each round the wound bleeds and a creature is within the area. The save DC is Constitution-based.

ECOLOGY

Environment Quasi-Plane of ObsidianOrganization solitaryTreasure none

In a quasi-realm where elemental water and elemental fire conjoin,
there exists a pocket plane known as the Quasi-plane of Obsidian; a
plane of barren wastes and blackened rock, of razor-sharp obelisks
and fields of sharpened glass. Creatures native to this plane appear as
blackened obsidian with jagged, serrated, or clear-cut angles and edges.
Some have barbed spikes adorning their elemental forms.

Obsidian quasi-elementals are usually encountered on their
home plane or on the Plane of Fire. Still some can be found on the
Obsidian Plain in the Plane of Molten Skies. Most, however, prefer the serenity that the
Quasi-plane of Obsidian offers, and thus they rarely venture forth unless
summoned.

Obsidian quasi-elementals are deadly combatants and strike with
their sharpened claws, ripping and tearing at their opponents. They are
relentless in their attacks and never give quarter.
